Discrete focal boundary-value problems
(Cambridge University Press (CUP), 2000-02-01)
In this paper we shall employ the nonlinear alternative of Leray-Schauder and known sign properties of a related Green's function to establish the existence results for the nth-order discrete focal boundary-value problem. ...
Singular problems modelling phenomena in the theory of pseudoplastic fluids
(Cambridge University Press (CUP), 2003-10-01)
Existence criteria are presented for nonlinear singular initial and boundary value problems. In particular our theory includes a problem arising in the theory of pseudoplastic fluids.
Existence criteria for singular boundary value problems with sign changing nonlinearities
(Elsevier BV, 2002-08-01)
Differential inclusions on proximate retracts of separable hilbert spaces
(Rocky Mountain Mathematics Consortium, 2006-06-01)
New existence results are presented which guarantee the existence of viable solutions to differential inclusions in separable Hilbert spaces. Our results rely on the existence of maximal solutions for an appropriate ...
Boundary value problems of nonsingular type on the semi-infinite interval
(Mathematical Institute, Tohoku University, 1999-01-01)
Existence of a positive solution is established for second order boundary value problems on the semi-infinite interval.
Nonlinear superlinear singular and nonsingular second order boundary value problems
(Elsevier BV, 1998-02-01)
Existence criteria for operator inclusions in abstract spaces
(Elsevier BV, 2000-01-01)
Fixed point theory for k–car sets

Existence of three solutions to integral and discrete equations via the leggett williams fixed point theorem
(Rocky Mountain Mathematics Consortium, 2001-03-01)
Criteria are developed for the existence of three nonnegative solutions to integral and discrete equations. The strategy involves using the Leggett Williams fixed point theorem.
